There are 2 types of analysis related to SLOSH.MEOW - (Maximum Envelope of Water) and MOM (Maximum of Maximum) The MEOW analysis represents the highest water due to a "family" of parallel tracks with the same direction, speed and intensity. The analysis is done for varying storm direction, speed of movement and category. For example a MEOW exist for a Cat 4 storm moving from the east at 12 mph into the Miami SLOSH basin. The MOM data is the "Maximum of Maximum or "Meows Of Meows". Simply put the MOM data represents the highest water due to a composite of MEOWs or the "worst case scenario" for the entire Slosh basin.
